247.17 Wed Sep 18 03:04:49 CEST 2019
25 - work around antique openssl version in RHEL 7 by formatting
26 dh parameters differently (reported by several people).
27 - add t/13_weaken.t.
28
297.16 Fri Jul 19 18:00:21 CEST 2019
30 - add ffdhe group dh parameters from RFC 7919, and use ffdhe3072
31 as new default, instead of schmorp1539.
32 - AnyEvent::Log did not reassess logging status of
33 AnyEvent::Log::logger's when contexts were changed with
34 ->attach/detach/slaves, causing them to not log even though a
35 recent attach should have caused them to log.
36 - added some more logging configuration examples.
37 - mention RFC 8482 in AnyEvent::DNS.
38
397.15 Tue Feb 26 03:07:42 CET 2019
40 - INCOMPATIBLE CHANGE: AnyEvent::Handle's tls_detect documentation gave
41 separate major and minor versions, while code passed only a single
42 value. This version follows the documentation and now passes separate
43 major and minor values.
44 - work around Net::SSLeay not having been ported to openssl 1.1, but many
45 distributions compiling it against openssl 1.1, which unfortunately
46 succeeds and results in a very broken module.
47 - AnyEvent::DNS::dns_unpack now stores the original DNS packet
48 in the __ member, to allow decoding of undecodable resouce records
49 containing compressed domian names.
50 - AnyEvent::Socket::parse_ipv6 would NOT, as advertised, accept ipv4
51 addresses. It now does and converts them to ipv4 mapped addresses.
52 - support CAA records, based on patch by Steve Atkins.
53 - add freenom and cloudflare nameservers as dns fallback.
54 - AnyEvent::Strict would not properly ward against io watchers
55 on files when the handle passed was a file descriptor.
56 - document "internal" variables used by the dns en-/decoder to allow
57 enterprising users to extend them in a semi-official way.
58
597.14 Sat Jun 24 01:44:19 CEST 2017
60 - fix a crash bug in AnyEvent::Handle with openssl 1.1.0 (patched
61 by Paul Howarth and apparently tracked down by Mike McCauley).
62 - AnyEvent::Handle->keepalive was documented (and defined) twice
63 (found by Matt Merhar).
64 - AnyEvent::Socket::tcp_bind/tcp_server would immediately unlink a unix
65 listening socket unless a guard is used. Change this so that no
66 cleanup will be performed unless a guard is used and document this more
67 clearly.
68 - make tcp_bind/tcp_server error messages more regular.
69 - work around latest perl upstream breakage - this time, perl5porters were
70 apparently bullied by a bogus CVE (CVE-2016-1238), and since distros
71 stupidly apply anything that has "security fix" stamped on it, it's likely
72 going to be a problem in practise (and working around it is trivial on
73 windows and unix).
74 - add TCP_FASTOPEN/MSG_FASTOPEN and MSG_NOSIGNAL/MSG_MORE/MSG_DONTWAIT
75 to constants.
76 - update warnings to common::sense 3.74 standards.
77
787.13 Sat Sep 17 04:31:49 CEST 2016
79 - Only call tlsext_host_name for non-empty common names (reported
80 by Maxime Soulé).
81 - log a (single) notice message if SNI is not supported.
82 - upgrade to UTS-46:9.0.0 draft and switch to non-transitional
83 behaviour, beating thunderbird, ie, edge, chrome and safari to it :)
84 (see also https://bugzilla.mozilla.org/show_bug.cgi?id=1218179)
85 - turns out the UTS-46 IDNA testcase failures were indeed bugs in the
86 testcases and the specification and not in the code - the post-9.0.0
87 unicode files have all known problems fixed, so finally the AnyEvent
88 IDNA implementation can pass the full IDNA testsuite - without needing
89 a single fix :)
90 - guarantee (and document) that condvar callbacks will be removed
91 on invocation - important to avoid circular references.
92
937.12 Wed Jan 27 19:12:26 CET 2016
94 - use common name as hostname for tls connects, if Net::SSLeay
95 supports SNI.
96 - fix documentation of tls_autostart read type in AnyEvent::Handle,
97 analyzed by Felix Ostmann.
98
997.11 Thu Jul 16 14:36:00 CEST 2015
100 - AnyEvent::Socket::parse_ipv6 could accept malformed ipv6
101 addresses (extra "::" at end and similar cases).
102 - add a more explicit warning to AnyEvent::Handle that it doesn't
103 work on files, people keep getting confused.
104 - new function AnyEvent::Socket::tcp_bind.
105 - new functions AnyEvent::fh_block and AnyEvent::fh_unblock.
106 - aligned ipv6 address formatting with RFC 5952 (by not shortening
107 a single :0: to ::).
108 - added stability canary support.
109
1107.09 Sat May 2 16:38:53 CEST 2015
111 - AnyEvent::Debug called an internal function (AnyEvent::Log::ft)
112 that was renamed to AnyEvent::Log:format_time. uinder its old name
113 (analyzed by Michael Stovenour).
114 - update AnyEvent::DNS fallback resolver addresses:
115 seems google effectively killed most other free dns resolvers,
116 so remove them, but add cable and wireless (ecrc) since it was
117 stable for 20 years or so, official or not, and there should be
118 an alternative to google.
119 - perl5porters broke windows error codes in 5.20, and mapped
120 WSAEWOULDBLOCK on the (different) EWOULDBLOCK error code, and
121 WSAEINPROGRESS into the incompatible ERINPROGRESS code, probably
122 because they were so cool. They probably broke other error codes
123 for no reason, too, but I didn't care for checking, it's too
124 depressing. This version only works around the WSAEWOULDBLOCK
125 issue, because I don't have a nice way to work around the
126 WSAEINPROGRESS bug.
127
1287.08 Wed Dec 10 05:27:17 CET 2014
129 - work around a newly introduced bug in Socket 2.011 (an
130 errornous sun_length check) (analyzed by Maxime Soulé).
131 - AnyEvent::TLS didn't load (but refer to) AnyEvent::Socket
132 (analyzed by Ben Magistro).
133 - AnyEvent::Strict will now confess, not croak. This is in line with
134 it being a development/debugging tool.
135 - work around a number of libglib bugs (debug builds of libglib enforce
136 certain undocumented behaviour patterns such as not being able to
137 remove a child watch source after it has fired, which we will try
138 to emulate to avoid "criticals". what where they thinking...).
139 - mention json security issues in AnyEvent::Handle, now that Douglas
140 Crockford has foolishly and incompatibly changed JSON.
141 - changed default dns resolver "max_outstanding" value from 1 to 10,
142 the latter beinfg the intended value all along
143 (reported by Ilya Chesnokov).
144 - added new "AnyEvent::Impl::UV" interface module to the UV event lib
145 (written by Mike Lowell).
146
1477.07 Tue Dec 17 17:45:02 CET 2013
148 - the documentation for custom tls verify schemes was wrong. make it agree
149 with the code (reported by Maxime Soulé).
150 - added cbor read and write types to AnyEvent::Handle (using CBOR::XS).
151 - work around an API change in openssl that could cause wrong tls connection
152 aborts, likely on windows only (analyzed by sten).
153 - calling AnyEvent->now_update with AnyEvent::Impl::Perl caused an
154 endless loop (reported by Dietrich Rebmann).
155 - add tlsv1_1 and tlsv1_2 protocols to AnyEvent::TLS
156 (patch by Maxime Soulé).
157 - document AnyEvent::Impl::IOAsync::set_loop and
158 $AnyEvent::Impl::IOAsync::LOOP. Though only documented now, this
159 functionality has _always_ been available.
160 - force a toplevel domain name in t/81_hosts.t (analyzed by
161 David Jack Wange Olrik).
162 - document that AnyEvent::Log uses AnyEvent::IO.
163 - warn about AnyEvent::Filesys::Notify performance.
164 - praise the joys of AnyEvent::Fork::*.
165 - time for an =encoding directive.
166 - do no longer use JSON to create a default json coder, use
167 JSON::XS or JSON::PP directly.
168
1697.05 Wed Aug 21 10:38:08 CEST 2013
170 - uts46data.pl couldn't be found due to wrong naming of the file
171 (reported by Fulko Hew).
172 - handle lone \015's properly in AE::Handle's default line read
173 (reported by various people).
174 - untaint ip addresses found in /etc/hosts (patch by José Micó).
175 - the memleak fix in 7.03 caused resolving via /etc/hosts to always
176 fail on first use (reported and testcase by Andrew Whatson).
177 - expose AnyEvent::Log::format_time, and allow users to redefine it.
178 - expose AnyEvent::Log::default_format, and allow redefinition.
179 - expose AnyEvent::Log::fatal_exit, to allow redefinition.
180 - AnyEvent::Debug shell can now run coro shell commands, if available.
181 - t/63* tests were wrongly in MANIFEST.
182 - kernel.org's finger server went MIA, switch to freebsd.org and
183 icculus.org.
184 - clarify that IO::AIO and AnyEvent::AIO are needed for AnyEvent::IO
185 to function asynchronously (reported by Daniel Carosone).
186 - hard-disable $^W in most tests, it generates too much garbage output.
187 - use a (hopefully) more future-proof method to emulate common::sense.
188 - upgrade to UTS-46:6.2.0.
189 - switch to INSTLIB from INSTLIBDIR, as INSTLIBDIR was wrongly
190 documented. should not affect anything.
191
1927.04 Thu Nov 15 02:23:58 CET 2012
193 - debugging code left in.
194
1957.03 Thu Nov 15 02:16:11 CET 2012
196 - AnyEvent::Socket::inet_aton did not work when dns resolution was
197 used to find the addresses (analyzed and patch by Maxime Soulé).
198 - fix a memory leak in the /etc/hosts lookup code when hosts don't
199 resolve and are not in hosts (analyzed by sten).
200
2017.02 Tue Aug 14 04:27:58 CEST 2012
202 - AnyEvent::Util::run_cmd could block indefinitely (analyzed and test
203 program by Yorhel).
204 - verified that AnyEvent::Socket follows RFC5952.
205 - try to parse "ADDR#PORT" in addition to "ADDR PORT".
206
2077.01 Sun May 13 01:03:17 CEST 2012
208 - fail with EPROTO in AnyEvent::Handle wqhen TLS is requested but
209 not available, instead of throwing an exception.
210 - use File::Spec to get the tmpdir in t/*, to avoid needless
211 failures on (most, not mine :) windows boxes.
212 - new handle read types: tls_detect and tls_autostart.
213
2147.0 Fri Apr 13 06:33:30 CEST 2012
215 - child watchers are broken in POE 1.352 (also many earlier
216 versions) and there seems to be no way to work around it, as POE
217 itself is inherently racy. Document this regression and add a delay
218 in t/68_poe_03_child.t for the time being.
219 - new module AnyEvent::IO, that is a frontend to either a pure-perl
220 synchronous I/O implementation (AnyEvent::IO::Perl), or to the
221 asynchronous I/O extension IO::AIO (AnyEvent::IO::IOAIO).
222 - load /etc/hosts only when DNS has no answer.
223 - stat /etc/hosts on every access and reload it if it changed.
224 - load /etc/hosts via AnyEvent::IO - potentially asynchronous.
225 - fix a buggy croak in the dh parameter reading in AnyEvent::TLS.
226 - AnyEvent::Log log_to_file and log_to_path now use AnyEvent::IO. As
227 a side effect, they now use true appending as opposed to libc
228 appending, and the file might not have been opened when the function
229 returns.
230 - the default logging level was not properly documented in a variety of
231 places, this has hopefully been rectified.
232 - updated uts46data.pl for unicode 6.1.0.
233 - made log messages generated by AnyEvent submodules not
234 include the package name anymore, as it will be logged
235 by default already.
236 - upgrade to the trick used by common-sense 3.5 to work
237 around extra warning torture/breakage under perl 5.15.x.
238 - log messages by anyevent are now ucfirst, are usually full
239 sentences and do no longer include the package name.
240 - the storable read type would sometimes throw an exception instead
241 of causing EBADMSG (analyzed by Maxime Soulé).
242 - work around a bug in openssl 1.0.1 which enforces a minimum rsa
243 keysize (reported by Paul Howarth).
244 - documented Rocco fabricating statements about AnyEvent and me.
245
2466.14 Tue Jan 31 20:00:24 CET 2012
247 - AnyEvent::Impl::Tk was broken due to a mysterious "die" inside,
248 probably an editing mistake (reported by Darin McBride).
249
2506.13 Thu Jan 12 07:27:01 CET 2012
251 - AnyEvent::Util::fork_call checked for POSIX availability in the wrong way,
252 causing it to fail if POSIX wasn't loaded already (analysed by Rock Power).
253 - AnyEvent::Handle::push_read (line => did pass $1 directly, so
254 regex-matching inside the callback would change the parameter, despite
255 $1 being dynamically scoped per-block. this perl bug is now being
256 worked around (testcase by Cindy Wang).
257
2586.12 Mon Dec 12 13:21:10 CET 2011
259 - $! was clobbered by subsequent calls in tcp_connect, due to
260 the postpone not saving/restoring it (analyzed by Richard Garnish).
261
2626.11 Tue Nov 22 10:36:05 CET 2011
263 - Tk cannot create windows when tainted unless you set a title, so
264 set a dummy title for AnyEvent's dummy mainwindow. How dummy.
265 - escape any nonprintable/nonascii characters when stringifying
266 backtraces.
267 - log the reason loading an interface module fails to load at level debug.
268
2696.1 Tue Oct 4 19:44:30 CEST 2011
8 - INCOMPATIBLE CHANGE: the default log level is now "3" (critical 270 - INCOMPATIBLE CHANGE: the default log level is now "4" (error
9 and above), and some emssages inside AnyEvent have bene elevated 271 and above), and some messages inside AnyEvent have been elevated
10 to critical, so. 272 to higher log levels to print by default.
273 - AnyEvent::log, unlike AnyEvent::Log::log, did not always exit on fatal.
274 - work around yet another signal race bug, newly introduced by POE. My
275 how that module sucks.
276 - add google public ipv6 dns as fallback servers, so AE::DNS can finally
277 support ipv6-only operation even with defaults (also use ::1 instead
278 of 127.0.0.1).
11 - give guidelines on how to chose a logging level. 279 - give better guidelines on how to chose a logging level.
280 - AnyEvent::Log can now cap (limit) log message priority by context.
281 - AE::log will now save and restore $! and $@, so callers don't have to.
282 - AE::Strict now checks that registered fds are still valid at regular
283 intervals.
284 - skip frequently called 'require' calls if the module appears loaded.
12 - increase signal latency test timer considerably for poor little osx. 285 - increase signal latency test timer considerably for poor little osx,
286 which can't be bothered with basic posix functionality such as signal
287 delivery.
13 - mention some debugging aids in the tutorial. 288 - mention some debugging aids in the tutorial.
289 - new env variable PERL_ANYEVENT_MAX_SIGNAL_LATENCY.
290 - private (%namespace) log contexts in PERL_ANYEVENT_LOG now have the name
291 of the context as title.
292 - AnyEvent::Strict would not restore read-write access to $_ when a callback
293 died - this is a user bug, but since AE::Strict exists to help dbeugging...
294 - detect the extremely evil IO::Async::Loop::AnyEvent module and refuse
295 to work with it - the author is well aware of the issues but refuses
296 to fix them. This extreme step has been taken because the module actively
297 attacks the goals of AnyEvent and makes it harder for module authors to use
298 AnyEvent.
